Beta Decay of Strontium: Yttrium Ionisation?

In summary, during beta decay of strontium, the neutron in the atom becomes a proton and an electron, causing the electron to leave the atom. This results in the formation of ionized yttrium, as it now has one more proton than electron. This is an important factor to consider when calculating the energy released during beta decay.

During beta decay (eg of strontium) a neutron becomes a proton and an electron. The electron then leaves the atom. The atom (yttrium) must then have one more proton than electron so does beta decay of strontium always leave IONISED yttrium?

Yes, that's correct. The daughter molecule will initially be postively ionized, and the beta particle will generally be too energetic to be re-captured by the daughter. In fact, this must be taken into account when you're working out the energy released during beta decay.
 

1. What is beta decay?

Beta decay is a type of radioactive decay in which a nucleus emits a beta particle (an electron or positron) and transforms into a different element.

2. What is strontium?

Strontium is a chemical element with the symbol Sr and atomic number 38. It is a soft, silvery-white metal that is highly reactive and found in various minerals.

3. What is yttrium ionisation?

Yttrium ionisation refers to the process of a yttrium atom losing one or more electrons to become a positively charged ion.

4. How is beta decay of strontium useful?

Beta decay of strontium is useful in a variety of applications, including nuclear medicine, industrial radiography, and radioactive dating. It is also used in the production of yttrium-90, which is used in cancer treatments.

5. Is beta decay of strontium dangerous?

Beta decay of strontium can be dangerous if proper safety precautions are not taken. The emitted beta particles can cause damage to living tissue and can be harmful if ingested or inhaled. However, with proper handling and containment, beta decay of strontium can be safely utilized for its various applications.
